FLUSHING-TANK.

Application filed November 25, 1913. Serial No. 802,857.-

Be it known that 1, WILLIAM A. KEEN, a citizen of the United States,residing at Baltimore, inthe State of Maryland, have invented certainnew and useful Improve ments in Flushing-Tanks, of which the followingis a specification.

This invention relates to improvements influshing tanks and has for anobject to provide improved means for controlling .the

, supply of water to the tank and the outlet of the Water from the tank.

Another object is to provide improved means to control the outlet ofwater fromthe tank, whereby valved outlets will be dis-- pensed withtogether with their objectionable features.

'A further object of the invention is to provide a flush tank with an.automatic water supply and a-siphon outlet and to provide improved meansfor actuating the same. I

Anotherobject is to provide an improved float controlling means toeflect' a shut-ofl' of the water supply and to cause an actuation of thesupply means.

With these and other objects in view the invention is illustrated in theaccompany- 'ing drawings, wherein,

,Figure 1, shows a vertical longitudinal 1 section through a tank havingmy improved devices attached thereto. Fig. 2, illustrates the same intop plan view. Fig. 3, shows a cross-sectional detail through thefloatrode the section being taken on the line 3-3 of Fig. 1. Fig. 4, shows asimilar section taken Referring to the drawings by numerals, 1,

designates a tank having a metal lining, 2, with a water supply pipe, 3,entering the tank and controlled-by avalve, 4, which in' many respectsis of ordinary commercial construction. The nozzle, 5, however, of

a partition, 6, and a feed pipe, 7, leads sald valve-to convey water fora purpose' presently to be described.

The supply valve, i, has an; operating arm; 8, to which the rod, 9, of afloat, 10,is at; tached. This arm is provided with a tubulan sleeve, 11,which has two stop shoulder s,-12,' and 13, at its forward end,asclearly shown in Fig. 8 of the drawing, The float,rod,l9',;

has its end extending loosely through; the

sleeve, 11-, so it mayroft'ate therein and aunt,

vents withdrawal of the latter from the sleeve.

14, on the projecting end of the rod prea extends downwardly, as shownin Fig.1?) of the drawlng. This arm is provided vat one side with a stopSlug, l6, whichhas position sleeve, 11, whereby the rod, 9, may rotatewhich is rigid thereon and which normally 1 between the stop lugs, 12,and18, onl,the i in the sleeve through an arc equalto the dis-.

tance between the lugs, 12, and 13,, as shown 1n broken lines in Fig. 3.The float rod, 9, has a and the sleeve, 11, at its inner end as shown 1ndetail in Fig. 7 of the drawing.

17, therein intermediate the float, 10, at'its f outer end- I u I oint,17,.perm1ts the outer member, 18-, of

the float rod to swing'upwardly while the:

rod is rotated in the sleeve but prevents said rod member from swingingup when the rod is in the position shown. in Figs. 1 and-2.

A rock-bar, 19, is mounted on the tank, 1,

in the present instance,'-so thatan operating chain, 20, may be attachedto the outer end thereof, while a. link rod, 21, connects the inner endof saidfrock-bar with the arm, 15,.

on the float rod,.as clearly seen inFig. 1 It will therefore be seenthat when the chain,

20, is pulled down, the link rod, 21, will swing arm, 15, up andtherebygive a partial rotation to the float rod, 9, and the hinge joint, 17.This-partial rotationjwill change the positions of the arm, 15;hinge-j'oint-,'17,

and float, 10, so the same. will assume posi-.

tions'indicated by broken lines in Figs. 3, 4 and 5 and when the joint,17, is soturned th-eouter member, 18, ofthe floatrod-will' immediatelyswing up because of the fhuoy-- I ancy of'the float, 10, whereupon the;operating arm, 8, of-the valve, 4, will drop to the.

position shown in broken lines inFig; l, 'andc allow plunger, 22, ofthevalve to raise and supplyrwaterif to the tank. through nozzle, 5.

ln front of theforward end of thesleeve,

The float, 10, is provided with a weight, 29, which when the operatingchain, 20, is released, will cause the float to turn back to its normalposition so as to reset the joint, 17, in the float rod.

The outlet of water from the tank is to be effected through a siphontube, 23. This siphon tube extends through the bottom of the tank andconnects with an elbow, 24, at the upper end of a flush pipe, 25. On theinterior of the tank, the siphon tube extends vertically and has a backbend, 26, from which a short leg, 27, extends toward the bottom of thetank. This short leg has an open lower end which terminates above thebottom of the tank so that when the water level in the tank lowers to apoint where the said open end is exposed the siphon action will bebroken and discontinued.

The water feed-pipe, 7, from the supply valve extends upwardly and has anozzle, 28, which enters the short leg, 27 of the siphon tube just belowthe back bend, 26, so that when water is supplied to the tank from thevalve, 4, a stream of Water will be directed from nozzle, 28, of thefeed pipe toward the back bend, 26, to cause the water to flow over saidbend.

When the device is in readiness for operation the tank will of coursecontain water,- the level of the water being just below the bend, 26,when the float cuts off the supply from the valve, 1. At this time theleg, 27, of course, will be filled with water up to the level in thetank while the tube, 23, will be empty. Of course pipe, 7, will also befilled with water because its lower end will be exposed at the nozzle,5, while its other or nozzle-end will be exposed to the water in theleg, 27, inasmuch as it is located below the normal water level.

lVhen the chain, 20, is pulled down, link rod, 21, will move up and arm,15, will also swing up so as to partially rotate float rod, 9;hinge-joint, 17, and float, 10. This partial rotation of the float rodand float will turn the hinge joint so it can break, as shown in brokenlines in Fig. 1, whereupon the rod,

9, and valve arm, 8, will lower and plunger, 22, will rise so as toadmit water through valve, 4:. The admission of water through the valvewill produce a supply in the feed pipe, 7, so that water will beprojected from the nozzle, 28, into the leg, 27, of the siphonimmediately below the water line and also below the normal water level.This supply of water through nozzle, 28, will cause an overflow of thewater in the bend of the siphon and thereby set the siphon in action sothat the water will flow out through the siphon faster than it can flowin through the nozzle, 5. This overflow will then continue until thelower end of leg, 27, is exposed when the siphon will be broken and theoutflow of water cease. After the rod, 9, has

water and the weight, 29, on the float will cause the latter to rotateback to its normal position to reset the hinge. As the water then risesin the tank the float will rise therewith and when the proper level hasbeen reestablish'edwthe float will cut otl' the inlet of water from thevalve, 4:.
